JAY GERKEN, CFA Chairman, President and Chief Executive Officer Dear Shareholder, In an effort to jump-start a weak economy, the Federal Reserve reduced short-term interest rates again in late June, driving the federal funds rate(i) to just 1%, its lowest level since the Eisenhower Administration. During this declining-rate environment, yields on fixed-income securities continued to decline from April through June. Meanwhile, many states, including California, have been grappling with budget deficits brought on by the faltering economy, layoffs and declining incomes -- all leading to lower tax revenues. Shortly after the Fed eased rates in June, long-term bond yields experienced a sharp reversal over the summer. However, the yields on shorter-term municipal fixed-income securities continued to fall and eventually stabilized throughout the remainder of the period. In this environment, the fund performed as follows: Smith Barney Muni Funds: California Money Market Portfolio's Performance As of September 30, 2003, the seven-day current yield and seven-day effective yield, which reflects compounding, of Class A shares of the fund were both 0.49%.(1) These numbers are the same due to rounding. The seven-day effective yield is calculated similarly to the seven-day current yield but, when annualized, the income earned by an investment in the fund is assumed to be reinvested. The effective yield typically will be slightly higher than the current yield because of the compounding effect of the assumed reinvestment. Please note that your investment is neither insured nor guaranteed by the Federal Deposit Insurance Corporation ("FDIC") or any other government agency. Although the fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in a money market fund. Certain investors may be subject to the federal Alternative Minimum Tax, and state and local taxes may apply. Capital gains, if any, are fully taxable. Please consult your personal tax adviser. (1) The seven-day current yield and seven-day effective yield, which reflects compounding of Class Y shares of the fund were both 0.63%. Performance for all of the fund's share classes can be found in the Financial Highlights section in this report. 1 Smith Barney Muni Funds | 2003 Semi-Annual Report - -------------------------------------------------------------------------------- CLASS A SHARES' YIELDS AS OF SEPTEMBER 30, 2003 - -------------------------------------------------------------------------------- Seven-day current yield 0.49% - -------------------------------------------------------------------------------- Seven-day effective yield 0.49% - -------------------------------------------------------------------------------- These numbers are the same due to rounding.

Please consult your personal tax advisor. - -------------------------------------------------------------------------------- At times of uncertainty such as these, investments in short-term fixed-income securities are an effective means of diversification in an overall investment portfolio. And municipal securities can provide income free from federal, and sometimes state and local, income taxes. Accordingly, we believe it is important to develop and stick with a long-range plan. Please work closely with your financial adviser to determine your proper asset allocation based on your risk/reward profile to help you pursue your long-term financial goals. As always, thank you for entrusting your assets to us. We look forward to helping you continue to meet your financial goals. Sincerely, /s/ R. Jay Gerken R.

========================================================================================================== (a) All ratings are by Standard & Poor's Ratings Service ("Standard & Poor's"), except for those identified by an asterisk (*), which are rated by Moody's Investors Service ("Moody's"). + Security has not been rated by either Standard & Poor's or Moody's. However, the Board of Trustees has determined this security to be considered a first tier quality issue due to enhancement features; such as insurance and/or irrevocable letters of credit. ** Aggregate cost for Federal income tax purposes is substantially the same. See pages 11 and 12 for definitions of ratings and certain abbreviations. See Notes to Financial Statements. 10 Smith Barney Muni Funds | 2003 Semi-Annual Report ================================================================================ Bond Ratings (unaudited) ================================================================================ The definitions of the applicable rating symbols are set forth below: Standard & Poor's Ratings Service ("Standard & Poor's") -- Rating "AA" may be modified by the addition of a plus (+) or minus (-) sign to show relative standings within the major rating categories. AAA -- Bonds rated "AAA" have the highest rating assigned by Standard & Poor's. Capacity to pay interest and repay principal is extremely strong. AA -- Bonds rated "AA" have a very strong capacity to pay interest and repay principal and differ from the highest rated issue only in a small degree. Moody's Investors Service ("Moody's") -- Numerical modifiers 1, 2 and 3 may be applied to each "Aa" rating, where 1 is the highest and 3 the lowest ranking within its generic category. Aaa -- Bonds rated "Aaa" by Moody's are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as "gilt edge." Interest payments are protected by a large or by an exceptionally stable margin, and principal is secure. While the various protective elements are likely to change, such changes as can be visualized are most unlikely to impair the fundamentally strong position of such bonds. Aa -- Bonds rated "Aa" are judged to be of high quality by all standards. Together with the "Aaa" group they comprise what are generally known as high grade bonds. They are rated lower than the best bonds because margins of protection may not be as large as in "Aaa" securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risks appear somewhat larger than in "Aaa" securities. ================================================================================ Short-Term Security Ratings (unaudited) ================================================================================ SP-1 -- Standard & Poor's highest rating indicating very strong or strong capacity to pay principal and interest; those issues determined to possess overwhelming safety characteristics are denoted with a plus (+) sign. SP-2 -- Standard & Poor's rating indicating satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes. A-1 -- Standard & Poor's highest commercial paper and variable-rate demand obligation (VRDO) rating indicating that the degree of safety regarding timely payment is either overwhelming or very strong; those issues determined to possess overwhelming safety characteristics are denoted with a plus (+)sign. VMIG 1 -- Moody's highest rating for issues having a demand feature -- VRDO. MIG 1 -- Moody's highest rate for short-term municipal obligations. P-1 -- Moody's highest rating for commercial paper and for VRDO prior to the advent of the VMIG 1 rating. NR -- Indicates that the bond is not rated by Standard & Poor's or Moody's. 11 Smith Barney Muni Funds | 2003 Semi-Annual Report ================================================================================ Abbreviations* (unaudited) ================================================================================ ABAG -- Association of Bay Area Governments AIG -- American International Guaranty AMBAC -- American Municipal Bond Assurance Corporation AMT -- Alternative Minimum Tax BAN -- Bond Anticipation Notes BIG -- Bond Investors Guaranty CGIC -- Capital Guaranty Insurance Company CHFCLI -- California Health Facility Construction Loan Insurance CONNIE LEE -- College Construction Loan Insurance Association COP -- Certificate of Participation CSD -- Central School District EDA -- Economic Development Authority EFA -- Educational Facilities Authority ETM -- Escrowed To Maturity FGIC -- Financial Guaranty Insurance Company FHA -- Federal Housing Administration FHLMC -- Federal Home Loan Mortgage Corporation FLAIRS -- Floating Adjustable Interest Rate Securities FNMA -- Federal National Mortgage Association FRTC -- Floating Rate Trust Certificates FSA -- Financial Security Assurance GIC -- Guaranteed Investment Contract GNMA -- Government National Mortgage Association GO -- General Obligation HDC -- Housing Development Corporation HFA -- Housing Finance Authority IBC -- Insured Bond Certificates IDA -- Industrial Development Authority IDB -- Industrial Development Board IDR -- Industrial Development Revenue IFA -- Infrastructure Finance Agency Inflos -- Inverse Floaters ISO -- Independent System Operator LOC -- Letter of Credit MBIA -- Municipal Bond Investors Assurance Corporation MERLOT -- Municipal Exempt Receipts Liquidity Optional Tender MFH -- Multi-Family Housing MSTC -- Municipal Securities Trust Certificates MUD -- Municipal Utilities District MVRICS -- Municipal Variable Rate Inverse Coupon Security PART -- Partnership Structure PCFA -- Pollution Control Finance Authority PCR -- Pollution Control Revenue PFA -- Public Financing Authority RAN -- Revenue Anticipation Notes RAW -- Revenue Anticipation Warrants RDA -- Redevelopment Agency RIBS -- Residual Interest Bonds RITES -- Residual Interest Tax-Exempt Securities SWAP -- Swap Structure TAN -- Tax Anticipation Notes TECP -- Tax Exempt Commercial Paper TFA -- Transitional Finance Authority TOB -- Tender Option Bond Structure TRAN -- Tax and Revenue Anticipation Notes UFSD -- Unified Free School District UHSD -- Unified High School District USD -- Unified School District VA -- Veterans Administration VRDO -- Variable Rate Demand Obligation VRWE -- Variable Rate Wednesday Demand XLCA -- XL Capital Assurance -

Significant Accounting Policies The California Money Market Portfolio ("Fund"), a separate investment fund of the Smith Barney Muni Funds ("Trust"), a Massachusetts business trust, is registered under the Investment Company Act of 1940, as amended, as an open-end management investment company. The Trust consists of this Fund and eight other separate investment funds: Florida, Georgia, Limited Term, New York, National, Pennsylvania, Massachusetts Money Market and New York Money Market Portfolios. The financial statements and financial highlights for the other funds are presented in separate shareholder reports. The significant accounting policies consistently followed by the Fund are: (a) security transactions are accounted for on trade date; (b) the Fund uses the amortized cost method for valuing investments; accordingly, the cost of securities plus accreted discount, or minus amortized premium, approximates value; (c) gains or losses on the sale of securities are calculated by using the specific identification method; (d) interest income, adjusted for amortization of premium and accretion of discount, is recorded on an accrual basis; (e) dividends and distributions to shareholders are recorded on the ex-dividend date; (f) class specific expenses are charged to each class; management fees and general fund expenses are allocated on the basis of relative net assets of each class or on another reasonable basis; (g) the Fund intends to comply with the applicable provisions of the Internal Revenue Code of 1986, as amended, pertaining to regulated investment companies and to make distributions of taxable income sufficient to relieve it from substantially all Federal income and excise taxes; (h) the character of income and gains to be distributed is determined in accordance with income tax regulations which may differ from accounting principles generally accepted in the United States of America; and (i) estimates and assumptions are required to be made regarding assets, liabilities and changes in net assets resulting from operations when financial statements are prepared. Changes in the economic environment, financial markets and any other parameters used in determining these estimates could cause actual results to differ. 2. Fund Concentration Since the Fund invests primarily in obligations of issuers within California, it is subject to possible concentration risks associated with economic, political, or legal developments or industrial or regional matters specifically affecting California. 16 Smith Barney Muni Funds | 2003 Semi-Annual Report ================================================================================ Notes to Financial Statements (unaudited) (continued) ================================================================================ 3. Exempt-Interest Dividends and Other Distributions The Fund declares and records a dividend of substantially all its net investment income on each business day. Such dividends are paid or reinvested monthly in Fund shares on the payable date. Furthermore, the Fund intends to satisfy conditions that will enable interest from municipal securities, which is exempt from regular Federal income tax and from designated state income taxes, to retain such tax-exempt status when distributed to the shareholders of the Fund. Capital gain distributions, if any, are taxable to shareholders, and are declared and paid at least annually. 4. Management Agreement and Other Transactions Smith Barney Fund Management LLC ("SBFM"), an indirect wholly-owned subsidiary of Citigroup Inc. ("Citigroup"), acts as investment manager to the Fund. Effective July 1, 2003, the Fund pays SBFM a management fee calculated at an annual rate of 0.475% on the first $1 billion of the Fund's average daily net assets; 0.450% on the next $1 billion; 0.425% on the next $3 billion of the Fund's average daily net assets; 0.400% on the next $5 billion and 0.375% on the Fund's average daily net assets in excess of $10 billion. This fee is calculated daily and paid monthly. Prior to July 1, 2003, the Fund paid SBFM a management fee calculated at an annual rate of 0.50% on the first $2.5 billion of average daily net assets; 0.475% on the next $2.5 billion and 0.45% on the average daily net assets in excess of $5 billion. This fee is calculated daily and paid monthly. Citicorp Trust Bank, fsb. ("CTB"), another subsidiary of Citigroup, acts as the Fund's transfer agent. PFPC Inc. ("PFPC") acts as the Fund's sub-transfer agent. CTB receives account fees and asset-based fees that vary according to the size and type of account. PFPCis responsible for shareholder recordkeeping and financial processing for all shareholder accounts and is paid by CTB. For the six months ended September 30, 2003, the Fund paid transfer agent fees of $198,002 to CTB. Citigroup Global Markets Inc. ("CGM"), another indirect wholly-owned subsidiary of Citigroup, acts as the Fund's distributor. All officers and one Trustee of the Trust are employees of Citigroup or its affiliates. 17 Smith Barney Muni Funds | 2003 Semi-Annual Report ================================================================================ Notes to Financial Statements (unaudited) (continued) ================================================================================ 5. Class Specific Expenses Pursuant to a Rule 12b-1 Distribution Plan, the Fund pays a service fee with respect to Class A shares calculated at an annual rate of 0.10% of the average daily net assets of that class. For the six months ended September 30, 2003, total Rule 12b-1 Distribution Plan fees, which are accrued daily and paid monthly, were $1,188,231. For the six months ended September 30, 2003, total Shareholder Servicing fees were as follows: Class A Class Y ================================================================================ Shareholder Servicing Fees $187,588 $0* ================================================================================ For the six months ended September 30, 2003, total Shareholder Communication expenses were as follows: Class A Class Y ================================================================================ Shareholder Communication Expenses $23,272 $0* ================================================================================ * Amount represents less than $1.00. 6. Distributions Paid to Shareholders by Class Six Months Ended Year Ended September 30, 2003 March 31, 2003 ================================================================================ Net Investment Income Class A $5,244,185 $19,311,225 Class Y 8 23 - -------------------------------------------------------------------------------- Total $5,244,193 $19,311,248 ================================================================================ 7. Shares of Beneficial Interest At September 30, 2003, the Trust had an unlimited amount of shares of beneficial interest authorized with a par value of $0.001 per share. The Fund has the ability to issue multiple classes of shares. Each share of a class represents an identical interest in the Fund and has the same rights, except that each class bears certain expenses specifically related to the distribution of its shares. 18 Smith Barney Muni Funds | 2003 Semi-Annual Report ================================================================================ Notes to Financial Statements (unaudited) (continued) ================================================================================ Transactions in shares of the Fund were as follows: Six Months Ended Year Ended September 30, 2003 March 31, 2003 ================================================================================ Class A Shares sold 4,267,943,546 7,983,425,382 Shares issued on reinvestment 5,249,020 19,660,865 Shares reacquired (4,359,762,096) (8,233,462,785) - -------------------------------------------------------------------------------- Net Decrease (86,569,530) (230,376,538) ================================================================================ Class Y Shares sold -- -- Shares issued on reinvestment 9 28 Shares reacquired -- -- - -------------------------------------------------------------------------------- Net Increase 9 28 ================================================================================ 8. Subsequent Event The Fund has received the following information from Citigroup Asset Management ("CAM"), the Citigroup business unit which includes the Fund's Investment Manager and other investment advisory companies, all of which are indirect, wholly-owned subsidiaries of Citigroup. CAM is reviewing its entry, through an affiliate, into the transfer agent business in the period 1997-1999. As CAM currently understands the facts, at the time CAM decided to enter the transfer agent business, CAM sub-contracted for a period of five years certain of the transfer agency services to a third party and also concluded a revenue guarantee agreement with this sub-contractor providing that the sub-contractor would guarantee certain benefits to CAM or its affiliates (the "Revenue Guarantee Agreement"). In connection with the subsequent purchase of the sub-contractor's business by an affiliate of the current sub-transfer agent (PFPC Inc.) used by CAM on many of the funds it manages, this Revenue Guarantee Agreement was amended eliminating those benefits in exchange for arrangements that included a one-time payment from the sub-contractor. The Boards of CAM-managed funds (the "Boards") were not informed of the Revenue Guarantee Agreement with the sub-contractor at the time the Boards considered and approved the transfer agent arrangements. Nor were the Boards informed of the subsequent amendment to the Revenue Guarantee Agreement when that occurred. 19 Smith Barney Muni Funds | 2003 Semi-Annual Report ================================================================================ Notes to Financial Statements (unaudited) (continued) ================================================================================ CAM has begun to take corrective actions. CAM will pay to the applicable funds $16 million (plus interest) that CAM and its affiliates received from the Revenue Guarantee Agreement and its amendment. CAM also plans an independent review to verify that the transfer agency fees charged by CAM were fairly priced as compared to competitive alternatives. CAM is instituting new procedures and making changes designed to ensure no similar arrangements are entered into in the future. CAM has briefed the SEC, the New York State Attorney General and other regulators with respect to this matter, as well as the U.S. Attorney who is investigating the matter. CAM is cooperating with governmental authorities on this matter, the ultimate outcome of which is not yet determinable. 20 Smith Barney Muni Funds | 2003 Semi-Annual Report ================================================================================ Financial Highlights ================================================================================ For a share of beneficial interest outstanding throughout each year ended March 31, unless otherwise noted: Class A Shares 2003(1) 2003 2002 2001 2000 1999 ===================================================================================================================== Net Asset Value, Beginning of Period $ 1.00 $ 1.00 $ 1.00 $ 1.00 $ 1.00 $ 1.00 - --------------------------------------------------------------------------------------------------------------------- Net investment income 0.002 0.008 0.016 0.030 0.025 0.026 Dividends from net investment income (0.002) (0.008) (0.016) (0.030) (0.025) (0.026) - --------------------------------------------------------------------------------------------------------------------- Net Asset Value, End of Period $ 1.00 $ 1.00 $ 1.00 $ 1.00 $ 1.00 $ 1.00 - --------------------------------------------------------------------------------------------------------------------- Total Return 0.22%++ 0.76% 1.66% 3.03% 2.49% 2.61% - --------------------------------------------------------------------------------------------------------------------- Net Assets, End of Period (millions) $ 2,302 $ 2,388 $ 2,618 $ 3,355 $ 3,095 $ 2,136 - --------------------------------------------------------------------------------------------------------------------- Ratios to Average Net Assets: Expenses(2) 0.61%+ 0.64% 0.63% 0.63 0.66% 0.64% Net investment income 0.44+ 0.76 1.67 2.97 2.46 2.55 ===================================================================================================================== Class Y Shares 2003(1) 2003 2002 2001 2000 1999 ===================================================================================================================== Net Asset Value, Beginning of Period $ 1.00 $ 1.00 $ 1.00 $ 1.00 $ 1.00 $ 1.00 - --------------------------------------------------------------------------------------------------------------------- Net investment income 0.003 0.010 0.018 0.031 0.025 0.026 Dividends from net investment income (0.003) (0.010) (0.018) (0.031) (0.025) (0.026) - --------------------------------------------------------------------------------------------------------------------- Net Asset Value, End of Period $ 1.00 $ 1.00 $ 1.00 $ 1.00 $ 1.00 $ 1.00 - --------------------------------------------------------------------------------------------------------------------- Total Return 0.33%++ 1.02% 1.78% 3.12% 2.57% 2.60% - --------------------------------------------------------------------------------------------------------------------- Net Assets, End of Period (000s) $ 3 $ 3 $ 3 $ 3 $ 2 $ 2 - --------------------------------------------------------------------------------------------------------------------- Ratios to Average Net Assets: Expenses(3) 0.53%+ 0.53% 0.54% 0.54% 0.55% 0.51% Net investment income 0.60+ 0.87 1.72 3.06 2.58 2.68 ===================================================================================================================== (1) For the six months ended September 30, 2003 (unaudited).
